Abstract: Disclosed is a method for producing an inorganic porous body having precisely controlled macropores concurrently with mesopores of a narrow pore size distribution. The method comprises dissolving an amphiphilic substance as template component in an aqueous solution containing a sol-gel reaction catalyst, adding an inorganic low molecular weight compound having hydrolysable functional groups to the solution, forming a gel including a solvent-rich phase for the macropores, drying the gel to remove the solvent, and removing the template component by such means as thermal decomposition.

Abstract: It is an object of the present invention to provide a simulation tool, which can overcome complications of examinations by simulations as described above and can provide a designer with easy examinations. A simulation based on a design parameter of a unit is implemented. Furthermore, a simulation result implemented by the control device is output on a display screen as a graph. Then, the unit design parameter is corrected in accordance with a correction in the graph displayed on the display screen. Thus, the simulation can be retried easily.

Abstract: An object of the present invention is to provide a column for chromatograph having a structure for enabling the separation of a sample and for maintaining a high resolution of separation. The present invention provides a column 3 for chromatograph having a honeycomb substrate 1 having a hole 1a for flowing a sample and a separation phase 2 filled in the holes 1a. Preferably, the separation phase 2 comprises a porous bone structure composed of an inorganic material and with open pores formed therein, and the porous bone structure is generated by sol-gel transition accompanied by phase transition.
